DUMP-CAR.

Specification of Letters Patent.

Patented Feb. 20, 1912.

Application filed September 27, 1909. Serial No. 519,865.

Be it known that I, HARRY S. HART, a citizen of the United States,residing at Chicago, in the county of Cook and State of Ilhnois, haveinvented certain new and useful Improvements in Dump-Cars, of which thefollowing is a specification.

The object of my invention is to provide a car of the type known as theHart convertible car with movable sides so formed that they may beeither adjusted to a vertical position or to an inwardly and downwardlyinclining position.

Cars of the type referred to are illustrated in Patents Nos. 689,583granted to Harry S. Hart, December 24, 1901, and 827,632, Harry S. Hartand others, July 31, 1906.

Cars of the type to which my invention is applied are provided with acentral longitudinal hopper, flat floor sections extending outwardlyfrom the hopper to the sides of the car and vertical sides'andadjustable ends. Means are provided for covering the central hopper inorder to transform the car into an ordinary gondola car, and to soadjust the parts as to uncover the central hopper, to incline the endsinwardly toward the central hopper, and in some instances to provideupward prolongations of the sides of the central hopper.

The nature of my improvement in, these cars will be apparent from thefollowing description and claims, taken in connection with theaccompanying drawings, in which- Figure 1 is a. cross sectional viewembodying one form of my invention. Fig. 21s a detail of the upper endof a flap or apron located between the side doors. Fig. 3 is a view ofthe structure adjacent one of the side stakes, looking from the insideof the car.

In cars of the type to whichnuy invention is applied, the sides areformed of doors hinged at their upper edges. It my pres ent purpose toso arrange the-structure that these doors may be moved inwardly on theirhinges to slope in the direction of the walls of the hopper bottom toform prolongations thereof.

In the car illustrated the superstructure comprises side stakes 26rigidly connected to the underframe and carrying at their upper endsside rails 25. In the present instance 1 have shown these side railsbuilt up from an I- beam and a wooden strip bolted together. The doors27 are hinged upon loo s 10 se -cured to the under sides of the ralls-25 by means of bolts 11 which secure the two parts of the side railstogether. The doors 27 may eitheroccupy a vertical position as shown atthe right of Fig. 1, may be swung inwardl to an inclined position asshown at the le t of Fig. 1, or may swing outwardly to permit thecontents of the car to be discharged through the sides thereof by meansof a plow, or otherwise. The floor of the car comprises stationaryhorizontal sections 6 proj ecting inwardly from the car sides to theouter edges of the central hopper. Aprons 35 are hinged to theunderframe of the car along the longitudinal edges of the central hopperand may be swung downwardly to a horizontal position as shown at theright of Fig. 1, covering the central hopper and forming a flat bottomcar, or may be lifted to the inclined position shown at the left ofFig. 1. When thejparts are adjusted as shown-at the left of Fig. 1, acenter dump hopper car is'formcd. This adjustment is effected by movingthe side sections 27 inwardly sufficiently to permit the aprons 35 to bemoved to a position outside of said sections 27, as shown at the left ofFig. 1. When so adjusted, the aprons 35 are held in the position. shownat the left of Fig. 1 by means of braces 30, and the side sectlons 27are in turn supported. upon the aprons 35.

The central hopper may be of a form now in common use, comprising a.stationary side 12 and a hinged side 13, hinged at 14 to the underframe.A chain 15 attached to the swinging section 13 at one end is at theother end attached to a winding shaft 16. Suitable means for rotatingthe windin shaft 16 permit the section 13 to be release for the purposeof dumping the load, and upon rotation of the winding shaft 16 in theUnless some provision be adopted, spaces Cl'i would beleft between thedoors 2'? when adjusted to the position shown. at the left of Fig. 1,such spaces being of the width o'l the side stakes which separate thedoors. 1 have, therefore, showi'i aprons 2E3 hung upon the loops 1.0which sup mrt the doors 2?, these aprons being of smnewhat greater widththan the Side stakes and lilppll'lg over the adjoining edges of the dome27. The upper ends of the aprons 28 are provided with eyelets, asillustrated in Fig. 2, these eyelets engaging the loops l0. llhen thedoors 27 are moved inwardly to the pos .ion shown at the left of Fig. 1,the aprons 28 will be carried with them, thus affording a closure of thespaces between the doors When the doors 27 are adjusted vertically shownat the right of Fig. 1, the aprons 538 will hang fiat against the doors,and when the doors aremoved outwardly, the aprons will be left behindand lying against the innerfaees of the side stakes.

It will he appav out from the 3ftthat I have provided a car whicl'i .uadjusted as an ordinary flat bottom ear with vertical sides and ends,and a laori zontal floor, and'that when so adjuswi the load may he "d ththe doors by 1': i w or cl The car may also be adjusted to pruide aeentral longitudinal hopper with slop Zing inwai ly and downwardly fromtheir upper er l. dump car coi'nprising side walls justahle to aninwardly and down -vainly sloping position, and a centralloi'igitudin'al hopper.
